How Online Buying Works

With the EPA’s R410A transition starting in 2026, Mitsubishi’s HM Series offers a rare 2025 buy-now window: closeout pricing on trusted Mitsubishi quality, whisper-quiet comfort, SEER2 up to 20, multiple sizes (9k–24k BTU), and a full 10-year parts warranty with registration. R410A’s A1 (non-flammable) safety rating is a plus for living-space installs, and you can save up to 40% on all units—shop remaining inventory while it lasts. Deal ends this year!

The Mitsubishi HM Series mini split continues to be one of the smartest home comfort investments in 2025.
